Key Takeaways
- Research shows that Electron Beam (eBeam) technology can effectively inactivate pathogens in ground turkey without affecting flavor.
- eBeam is a non-thermal method approved for “cold pasteurisation” that damages pathogen DNA, preventing replication.
- While effective, the oxidation potential of eBeam necessitates careful monitoring to maintain meat quality, especially in poultry.
Research on eBeam Technology in Poultry Safety
Microbial contamination in poultry products poses ongoing challenges for food safety. A recent study published in “Poultry Science” evaluated the use of Electron Beam (eBeam) technology to enhance microbial safety while maintaining meat quality.
eBeam is a non-thermal process using high-energy electron beams that damage the DNA of pathogens, making it effective for germ control. This technology, alongside X-rays and gamma rays, is approved by the U.S. Food and Drug Administration for a method referred to as “cold pasteurisation”. Although effective in controlling pathogens in various foods, there is limited data on its application in poultry.
The research aimed to target ground poultry, recognized as a significant source of Salmonella and Campylobacter in food recalls. Conducted at Texas A&M University’s National Center for Electron Beam Research, this study utilized the world’s largest electron beam irradiator.
Palmy Jesudhasan, a research microbiologist at the U.S. Department of Agriculture, stated that eBeam primarily serves sterilisation purposes, shredding the genetic material of harmful bacteria and preventing their replication. While it can effectively combat bad bacteria, its oxidizing effects require careful monitoring, particularly due to poultry’s higher levels of unsaturated fats, which make it prone to oxidation.
Casey Owens, a meat scientist at the University of Arkansas, emphasized the importance of meat quality testing to monitor oxidation levels. High oxidation can lead to off-flavors and odors that consumers find unappealing.
The study compared the effects of eBeam on turkey and chicken. Ground turkey was packaged in a modified atmosphere, which helped slow oxidation and showed promising results in terms of pathogen inactivation and meat quality preservation. However, some undesirable notes were noted in chicken meat.
The authors concluded that eBeam technology presents a viable intervention strategy to boost microbial safety in poultry while minimizing negative impacts on meat quality. The study indicated that a dose of 3 kilogray effectively achieved a 99.99% reduction of Salmonella and Campylobacter in commercially packaged ground poultry meat.
This research heralds a significant advancement in food safety technology, highlighting both the potential and considerations necessary for successfully applying eBeam to poultry products.
